IMPROVEMENT IN SEEDING-MACHINES.

'To WHoM IT MAY coNoERN:

Beit known that I, MARTI-N HAXDEN, of Detroit, in the county of Wayne, and State of Michigan, have invented a new Iand useful4 Improvement in Seeding-Machine, to be used for all kinds of seed, and 'with or without a cultivntor or drill; and I do hereby declare that the following is a true and exact description of the same, referencebeiug had to the accompanying drawings, and to the' letters of reference marked thereon., and making a part of this specification.

Figure 1 is a perspective view, showing the front and bottom of my inventio'n.`

Figure 2 is a-viewof the interior andhottdm of the seed-box or hopper:

Figure Bis a vertical sectionalfviewof the cylinder and'attachments upon the line a: a'.

The object of my invention .is so to construct a seeding-machine-that it can be more readily gauged to suit the kind and quantity of seed'desired to be` sown npon a given surface, as, by my invention, the smallest es well as the greatest quantityrequ'ired may be evenly distributed.

I will now proceed to describe the method of manufacturing my invention, so that th"ose skilled in the art ca'n readily build the same, especial/ reference'heing had to the drawings.

I tiret make the hopper o r seedfbox A, of any desired capacity, fastening upon the bottom thereof the couvex 'cap C.. Beneath the cap C, I place the'revolving. shaft B, and attach the same to the hopper or seed-box at the ends thereof, by.any suitable device. Upon the shaft B, I place the grooved cylinder E, and fasten it to the shaftby keys or otherwise, so that the shaft and cylinder will revolve together. A Then I slip on to the shaft the collar P,4 provided with gauge-prongs F, which fit and work in the grooves G in the cylinder E. .Around .this cylinder I place the sleeve D, with a rectangular-opening in the bottom, as shown in g. 1. and an inclined opening, as shown in iig.' 2, in the top. The-rectangular opening is for.: the delivery of the seed, while the inclined opening acts as s strike to the grooves G, and prevents the'possibility of delivering any more seed than is required. The lower .poiht of the inclined opening should be connected with the corresponding corne;` of the rectangular opening, by asmall slot, R, to prevent crushing or bruising any seed that `may be'eanght at that point.4 L is e. plate, provided with arms M, which catch upon the shaft B, by which to govern the position of the gauge-prongs F. This platelis attached to the bottom ,of the hopper bye. proper button or screw, 0, which works in the slotvN., to' allow the plate to move forward or back, as occasion may require'. The plate is also provided with a rack, K, into the teeth of which mesh the teeth of the segment-rack J, which is attached to the lever I, which is provided with a suitable pin, ley-which its position is fixed by dropping into the holes or notches in the quadrant H. This adjusting-apparatus is very simple,xand consists in moving the lever I, and dropping the pin attached thereto into any one of the holesor notches in the quadrant, by means of which the gauge-prongs are made to advance or recede in the grooves in the cylinder,and govern the amount of seed tobe delivered. The holes or notches in the quadrantfshould-be so marked as toindicate the quantity of seed required. The shaft B may be made to revolve by any appropriate device. Another'object in making the inclined opening in the top'of the sleeve is, that while f striking,Y it does it with a drawing stroke, and consequently does not inliure the. seed. The .cylinder is so constructed and attached to the shaft that itnot only revolves with the shaft, hat the shaft is allowed toslide horizontally through the cylinder, while the cylinder is held in its proper position rela'tive to the-openings in the sleeve, by a flange, S. i v

The same letters indicate like ports in each figure.

What I claim as my invention, and desire to secure by Letters Patent, is-

'1.,Tho construction of a seeding-machine, provided with'the shaft B, the grooved cylinder E, the collar P, provided with tho gange-prongs F, and the sleeve D, when'constructed and operating substantially as herein.- before described.v 4

'2. The quadrant H, the lever I, the `segment-rack J, and the plate L, when attached and operating substantially as and for the purposes set forth. v 5

3. The combination of all the foregoing-described parte, in conjunction with the hopper or seed-hex A, when constructed and operating substantially as and for the purposes specified.
